is marguerite yellow, and the raised disc rosolane pink which 
extends from the column-foot to the very lip. 
A species doubtless belonging in the group with Dendrobium 
O’Brienum Kranzl. and Dendrobium amethystoglossum Reichb. 
f. It is especially close to the first but differs in its much shorter 
and few-flowered racemes, in the spur, and especially the label- 
lum. 
This species is dedicated to Dr. Leon Ma. Guerrero, chief of 
the division of botany of the Bureau of Science and specialist in 
Philippine medicinal plants. The junior author greatly appre¬ 
ciates the encouragement Doctor Guerrero has given him during 
the prosecution of these studies.
